My 2019 Toyota Hybrid lists 0W16 as its preferred motor oil. Toyota’s 0W16 is the only 0W16 that I see that you have tested. Do you plan on testing others?
Would the Amsoil Signature 0W20 be a good substitute? Amsoil only makes 0W16 in there OE series.

Hi Robert,
I have no plans to test any more insanely thin 0W16 oils. I do not support using oil so extremely thin, only in an attempt to squeeze out a microscopic improvement in mpg. Oil that thin is not beneficial to an engine in any way.
Amsoil Signature Series 0W20 would be a much better choice.
Thanks for your valued opinion about the Toyota 0W16 oil. I will definitely switch to the Amsoil Signature 0W20 oil at the next oil change. However 3 weeks ago I changed the oil at 5000 miles with the Toyota 0W16. Do you think it would be wise to add Oil Extreme Concentrate Additive to the Toyota 0W16 oil and leave it in for the next 5000 miles?
Thanks for taking the time and effort to help me.
Robert

Hi again,
Never use aftermarket motor oil additives. They upset the factory’s carefully balanced additive package, making the oil WORSE overall than it was to begin with, no matter what it may or may not do for an oil’s wear protection capability.
If your car is an ordinary daily driven vehicle that isn’t subjected to severe usage in the traditional sense, you can wait until the next oil change to upgrade the oil.
However, by definition, hybrids subject their oil to severe usage by NOT keeping their oil fully warmed up at all times. So, the oil is subjected to never-ending hot/cold cycles. That creates a situation where the normal condensation that is formed as cold oil warms-up, is never fully boiled off, thus leaving the oil and engine protection compromised. That is equivalent to endless short trips on an engine, which is one of the worst types of operation, and falls under the severe usage category.
Therefore, hybrids should follow the severe usage oil change interval of every 3,000 miles. The ridiculously long oil change intervals in the Owner’s Manual should be completely ignored if you want to provide your engine with the best protection.
